Definitions

  • the present disclosure relates to a safety device for controlling release of pressurized fluid from a vessel of the type having an open end with a closure removable for open access to the contents of the vessel.
  • Pressure vessels of this type are often employed for filtering fluid through filter elements disposed within the pressure vessel and which require periodic removal for cleaning or replacement of the filter.
  • the vessel typically contains an inlet and outlet connected in line in a fluid system for passing fluid under pressure through the filter elements contained within the vessel.
  • Such pressure vessels commonly employ a header or closure plate disposed over an open end of the pressure vessel and secured thereto by fasteners such as bolts or toggle clamps and sealed over the end of the pressure vessel by a seal such as an O-ring or gasket.
  • a leak in the closure or lid seal can permit undesired release of pressurized fluid and thus create a hazard to the user. Also, in the event the vessel is not completely de-pressurized before the operator initiates release of the fasteners or clamps a residual pressurized fluid escaping between the flange and the undersurface of the cover plate as the fasteners are released can create a hazardous condition for the operator.
  • a closure mechanism for a vessel having a lid disposed thereon is shown.
  • the closure mechanism has an annular member to radially enclose the vessel and the lid. On the inside of the annular member, a pivotable element for clamping the lid to a top portion of the vessel is provided.
  • a pressure vessel as set forth in claim 1 is provided. Further embodiments of the invention are inter alia presented in the dependent claims.
  • the present disclosure provides a solution to the problem of preventing hazardous escape of fluid under high pressure from a pressure vessel during operation in the event of seal failure; and, additionally upon the operator loosening of the fasteners of the pressure vessel closure or lid for removal thereof after opening a bleed valve for access to the interior of the pressure vessel.
  • the pressure vessel closure or lid has a flange extending peripherally thereabout and at generally right angle to the lid for directing fluid escaping between the lid and the pressure vessel in a direction generally parallel to the wall of the pressure vessel as the fasteners retaining the lid are released by the user, and thus in a direction away from the operator or user.
  • the closure is secured by swing bolts pivoted on the vessel wall and engaging open cutouts or slots in the closure.
  • Flow shields are provided on the swing bolts for redirecting fluid escaping at the slots and about the bolts for protecting the user from a blast of fluid under high pressure escaping in the region of the fasteners.
  • an exemplary pressure vessel assembly in accordance with the present disclosure is indicated generally at 10 and has a relatively thin walled pressure vessel member 12.
  • Vessel member 12 may have a generally circular transverse section and has an open end indicated generally at 14 with an annular flange 16 provided thereon, which flange has an annular groove 18 formed therein into which is received a resilient annular sealing member 20 such as an O-ring.
  • the vessel 12 may be provided with at least one fluid line connector fitting such as denoted by reference numeral 22 in FIGURE 2 for connection to a fluid pressure or flow line such as in the case where the pressure vessel is employed for containing a fluid filter (not shown). It will be understood that another unshown fluid fitting may be provided for inlet and outlet flow.
  • the pressure vessel member 12 has a lid or closure indicated generally at 24 which has in the exemplary version illustrated in FIGURE 2 , a generally concave central section with a relatively thick annular flange portion 26 disposed peripherally thereabout.
  • the flange 26 has provided therein a plurality of circumferentially spaced cutouts or slots 28 for receiving fasteners as will hereinafter be described.
  • the pressure vessel flange 16 has a plurality of radially outwardly extending circumferentially spaced lugs 30 provided thereon which have cross pins 32 with each pin having pivotally received thereon the eye portion of a swing bolt 34 which has the threaded portion thereof extending upwardly through the slots 28 in the flange 26 of the lid 24.
  • a cover plate indicated generally at 36 is received over the lid 24 and has a plurality of cutouts 38 formed thereon into each of which is received one of the swing bolts 34; and, lid or closure 24 is secured to the vessel 12 by a ringed nut 40 or alternatively a castellated nut threadedly engaging each of the swing bolts 34.
  • the cover 36 has a downwardly extending flange 42 provided thereon and extending about the periphery thereof.
  • the underside of which flange serves to deflect downwardly along the wall of vessel 12 the blast of pressurized fluid escaping between the undersurface of the cover flange 26 and the seal ring 20.
  • cutouts or slots 38 formed in the cover provide an open area for the blast of pressurized fluid to escape about the swing bolts 34 and through the cutouts 38.
  • fluid flow or blast shields are disposed about each of the slots 38 and over the swing bolts 34.
  • Shields 44 are configured, as will hereinafter be described, to be retained by the swing bolts and to function to direct flow escaping through slots 38 and about the swing bolts in a direction downwardly and away from the user or operator.
  • the cover 36 is shown with one of the blast shields 44 positioned over each of the slots 38 prior to assembly of the cover and shields over the swing bolts 34.
  • an exemplary blast shield 44 is shown as having a plate portion 46, the inner surface thereof being operable to receive and redirect in a downwardly direction high pressure flow escaping in the slots 38 and about the swing bolts 34.
  • the plate 46 has an inwardly extending rib 48 which may be formed integrally with plate 46 or affixed thereto as for example by weldment and which has provided thereon a hollow cylindrical portion 50 which is adapted to be received over one of the swing bolts 34.
  • the plate 46 has stiffening ribs 52, 54 provided thereon which extend upwardly therealong to the curved radially inwardly extending flange portion 54 formed along the upper edge of the plate 46.
  • each of the shields 44 covers one of the cutouts or slots 38 and one of the swing bolts 34 to prevent high pressure fluid escaping through the slots upon the user loosening the ringed nuts 40.
  • swing bolts 34 are shown in the released or downward position after loosening of nuts 40 and pivoting bolts 34 about pins 32 and out of slots 28 thus releasing the closure 24 for removal. Shields 44 are rotated with bolts 34.
  • the present disclosure thus describes a technique for enabling the cover or lid of a pressure vessel to be retained by swing bolts for quick release and removal by the user or operator.
  • a lid seal leak or any residual pressure in the vessel after de-pressurization, the escape of the high pressure fluid in the region of the slots for the swing bolts is deflected by blast shields attached to the swing bolts for covering the slots in the closure or lid.
